Question

Ada yg tau caranya? bantuin ya kaka

Answer 1

1. 60x80=4800
2.2500:4=AB
AB=625 cm
3. (60x40):2= 2400:2
=1200

Answer 2

1) 80x60 = 4800cm2
2) ab= √2500 cm
= 50 cm
3) L=1/2 x a x t
= 1/2 x 60 x 40
= 1200 cm2
4) 10x8 = 80 m2
5) L = 1/2 x d1 x d2
= 1/2 x 14 x 10
= 60 cm2
6) L = 1/2 x d1 x d2
1/2 x 16 x 21 = 168cm2
7) L= 1/2 x DB x AC
2500000 CM2 = 1/2 x20 x AC
5000000 = 20 x AC
250000 Cm = AC
8) L = 1/2 ( a+b) x t
3060 = 1/2 ( 100+70) x t
3060 = 85 t
36 = t
9) L = 22/7 x (21)*2
22 x 63 = 1386 m2
10) 154 = 22/7 x r2
1078 = 22 x r*2
49= r*2
7 = r
